- switching of the switching element 6 from the switching position A to the switching position B takes place without interruption of traction at initially open clutch 5, for example, to allow a transition from electrodynamic creep in the shift position A to electrical creep in the shift position B without interruption of traction.
- Such switching is required, for example, when a long time in the switching position A is a regenerative, electrodynamic creep and the state of charge of the electrical energy storage exceeds a critical limit. In this case, then must be changed to the switching position B and purely electrical creep done in which the electric machine 2 is operated by a motor, so as to discharge the electrical energy storage.
- the switching element A is the switching position A is inserted, the clutch 5 is open and the internal combustion engine 1 is running.
- a load transition from the electric machine 2 takes place on the clutch 5, the internal combustion engine 1 thus takes over the clutch 5, the drive torque of electric machine 2 completely, in which case at low driving speeds, the clutch 5 is operated in the slip.
- the shift position A can then be designed, wherein subsequently using a speed-controlled electric machine 2, the switching element 6 is synchronized relative to the switching position B, to subsequently insert the shift position B.
- a load transition from the internal combustion engine 1 to the electric machine 2 wherein on the electric machine 2, a load build-up and the internal combustion engine 1, a load reduction takes place.
- the clutch 5 is load-free by the load reduction on the engine 1, so that the clutch 5 can be opened without load. Subsequently, there is purely electrical creep, wherein the internal combustion engine 1 can be operated at idle speed or can be switched off.
